To create a more complex area with more than
four corners or a Tripwire, or to mask an area of
the video from motion detection, select the
manual selection icon .
•With Area selected, click in the video to create the first corner of the area. Continue adding
corners (up to 16), then select Finish to complete the area.
•With Tr ipw ire selected, click in the video to create the first point of the line. Continue to the
second point (and more if desired), then select Finish to complete the line.
Note
•With Masking Area selected, click in the video to create the first corner of the area. Continue
adding corners, then select Finish to complete the area.
This is motion detection masking; not privacy masking. The video image will still be seen, but
alarms will not be generated. Analytics will be disabled in the masked area. The purpose is to
manually define regions that will not generate motion alarms. For example, this can be helpful to
eliminate alarms from a tree or bush moving in the wind or to perform auto calibration for some
scenes.
Dependency
You can establish dependency between two analytics regions: The camera triggers an alarm when
an object is detected by one analytics region and then the other within a specified time period.
To establish dependency between two regions:
Step 1 Create the two analytics regions as described above.
Step 2 From the Regions list, select the first detection region and then select Dependency.
Step 3 From the drop-down menu under Dependency, select the second detection region.
The direction (left or right) for an alarm over a tripwire line is controlled by both the properties
of each tripwire and the direction in which the line was originally drawn. A direction to the right
is to the right of a person moving from the first point to the second point of the line, etc.
